[PATCH v2 net-next 0/3] rhashtable: Wildcard and scored lookups

[Tom Herbert <tom@herbertland.com>]

This patch set implements:
  - A compare function can be passed in the lookup. This allows for
    comparison to include "wildcard fields"
  - Order insertion within a bucket, so that entries with more specific
    information can be matched first.
  - Scored lookups. This is like the socket lookups. It allows
    different levels of matching, and returning one of N possible
    best matches with a uniform distribution based on flow hash.

Testing: Tested this in conjunction with ILA development. Will be
posting ILA patches shortly.

V2:
 - Added rhashtable_lookup_ordered_cmpfn to ensure that greatest
   ordered matching entry is found during rehashing
 - Minor cleanup to scored lookup patch

Tom Herbert (3):
  rhashtable: Allow lookup function to have compare function agument
  rhashtable: Add a function for in order insertion and lookup in
    buckets
  rhashtable: Add scored lookups
